Abstract: A turbocharger system may include a turbine housing and a tongue insert. The turbine housing may include an inlet, an outlet, and a gas pathway between the inlet and outlet. The gas pathway may include a volute portion and an inlet portion extending approximately tangent to the volute portion. The turbine housing may be formed from a first material. The tongue insert may be received in the turbine housing and may at least partially define the volute portion and the inlet portion. The tongue insert may be formed from a second material that is more heat resistant than the first material.

Abstract: An exhaust gas heat recovery system may include a housing, a valve member, and a heat exchanger. The housing may include an inlet, an outlet, a first exhaust gas pathway in communication with the inlet and outlet, and a second exhaust gas pathway in communication with the inlet and outlet. The valve member may be disposed within the housing and may be movable between first and second positions. In the first position, the valve member may allow fluid flow through the first exhaust gas pathway and substantially prevent fluid flow through the second exhaust gas pathway. In the second position, the valve member may allow fluid flow through the second exhaust gas pathway. The heat exchanger may be in communication with the second exhaust gas pathway and may include a conduit containing a fluid in thermal communication with exhaust gas when the valve member is in the second position.

Abstract: An exhaust manifold including a manifold body made of a first material and at least one heat shield insert provided inside the manifold body and made of a second material. The first material is a low cost material and the second material is a higher grade, temperature-resistant material. The manifold body includes a plurality of runners, collector and an outlet. The shield insert is preferably provided in the collector region adjacent to the outlet. The heat shield insert may have a curved sheet configuration or a tubular configuration depending on applications. The heat shield properly insulates the manifold body from the exhaust gas to protect the manifold body. The exhaust manifold, which is made from a combination of different materials, provides a more cost-effective solution in high temperature applications.

Abstract: A valve assembly may include a valve body, a valve member, and a valve shaft. The valve body may include an inlet, an outlet, and first and second fluid paths in fluid communication with the inlet. The first fluid path may extend axially through at least a portion of the valve body. The second fluid path may be defined by first and second annular walls and may at least partially surround the first fluid path. The valve member is disposed in the valve body and may be movable between a first position preventing fluid flow through the first fluid path and a second position allowing fluid flow through the first fluid path. The valve shaft may be fixed to the valve member and mounted to the valve body for rotation relative to the valve body.

Abstract: A exhaust component assembly includes an exhaust component and a divider plate. The exhaust component includes an inner wall defining a gas passageway. The divider plate is inserted in the gas passageway and secured to the exhaust component by mechanical locking means, generally in an interference-fit relationship.

Abstract: A component of an exhaust system may convey exhaust gas between one or more inlets and one or more outlets and may include at least one fluid path in thermal communication with the exhaust gas. The fluid path may be defined by an external surface of the component and a cover plate attached to the external surface. The fluid path may be connected to a coolant source.

Abstract: A combustion engine exhaust assembly. The assembly comprises an exhaust gas passageway that includes a divider plate assembly. The divider plate assembly includes a body and a divider plate wherein at least one of the body and the divider plate are generally formed from a material resistant to at least one of extreme temperature conditions, extreme thermal gradient conditions, and extreme loads. The divider plate assembly is useful in distributing exhaust gases within an exhaust assembly and is generally capable of extending the useful life of an exhaust manifold, for example.
